Tom, your remark about Matthew Henry surprised me, so I went to the online commentary site and I'll share something I'd not really thought about or seen in the past. On that site is the abbreviated, concise Matthew Henry Commentary, as well as the full unabridged Matthew Commentary. It appears to me that whoever did the Concise version, inserted their own ideas other than how Henry explained it in the unabridged version. Here are the two links:

The shorter Concise version reads as if from someone with a totally different view of this section of prophecy, than that of Matthew Henry himself. This alerts me to in the future be careful of Concise editions.
